+{% include releases/new-release-downloads-docker-image.md release=include.release %}
+
+<h3 id="v26-1-0-beta-1-security-updates">Security updates</h3>
+
+- We are adding a new flag
+   `--allow-debug-user` to the cockroach start command to explicitly allow
+   enabling the debug_user to log into the system. This flag is currently
+   experimental and is disabled by default. When not set, authentication
+   attempts by `debug_user` will be rejected with an error: `"certificate
+   authentication failed for user "debug_user""` for SQL connections and
+   `"failed to perform RPC, as debug_user login is not allowed"` for RPC
+   connections.
+  
+   This flag is intended for debugging and troubleshooting purposes and should
+   only be enabled when necessary for diagnostic operations. The debug_user
+   should be disabled when not actively in use.
+  
+   Note: Certificates must include "debug_user" as one of the principals
+   (CommonName or SubjectAlternativeName) for this functionality. The flag
+   controls whether such certificates are accepted for both SQL client
+   connections and RPC connections. [#158963][#158963]
+
+<h3 id="v26-1-0-beta-1-{{-site.data.products.enterprise-}}-edition-changes">{{ site.data.products.enterprise }} edition changes</h3>
+
+- Improved the description of the
+  changefeed.default_range_distribution_strategy cluster setting to better
+  explain the available options and their behavior.
+  
+  Epic: None [#158602][#158602]
+
+<h3 id="v26-1-0-beta-1-sql-language-changes">SQL language changes</h3>
+
+- `crdb_internal.index_usage_stats` and `crdb_internal.datums_to_bytes` are now available in the `information_schema` system catalog as `information_schema.crdb_index_usage_stats` and `information_schema.crdb_datums_to_bytes`, respectively. [#156963][#156963]
+- The `ALTER COLUMN ...` sequence identity
+  commands are run by the declarative schema changer. [#157030][#157030]
+- Added support for `EXECUTE SCHEDULE {schedule_id}` to allow immediate execution of a scheduled job. This does not apply to `ALTER BACKUP SCHEDULE`; attempting to execute a backup schedule will result in an error. [#158694][#158694]
+- `CREATE TYPE` with composite type syntax now supports array types in field definitions. For example, `CREATE TYPE t AS (a INT[])` and `CREATE TYPE t AS (a INT ARRAY)` now work correctly, matching PostgreSQL behavior. [#158888][#158888]
+- introduces the new STRICT option for locality aware
+  backups. When this flag is passed, the backup will fail if we attempt to backup
+  data that lives in a kv node with locality tag X into a bucket with a different
+  locality tag. [#158999][#158999]
+- adds STRICT STORAGE LOCALITY option to backup cmd.
+  Subsequent commit hooks it up to backup flow. [#158999][#158999]
+- CREATE CHANGEFEED FOR DATABASE statement will
+  return an error stating that the feature is not implemented. [#159000][#159000]
+- The `WITH RESOLVED TIMESTAMP` option can be passed to `SHOW JOBS` or `SHOW JOB` to include the resolved timestamp, if any, for the jobs in the output columns. [#159068][#159068]
+
+<h3 id="v26-1-0-beta-1-command-line-changes">Command-line changes</h3>
+
+- You can now specify a user-defined database user when generating `debug zip` and `debug tsdump` files. Use the `--user` and `--url` flags to set the username. Previously, these operations required the root user. This change provides backward compatibility by defaulting the username to `root`. This update is part of an ongoing effort to limit root user access. [#158961][#158961]
+
+<h3 id="v26-1-0-beta-1-bug-fixes">Bug fixes</h3>
+
+- Fixed a bug where issuing a noop schedule modification
+  could skip the next incremental backup
+  
+  Fixes: #158296 [#158820][#158820]
+- Fixed a bug that allowed a column to be dropped from
+  its table despite being referenced by a routine. The bug could happen when the
+  column was only referenced as a target column in the SET clause of an UPDATE
+  statement within the routine. This fix only applies to newly-created routines.
+  In versions prior to v26.1, the fix must be enabled by setting the session
+  variable `prevent_update_set_column_drop`. [#158935][#158935]
+- Fixed a bug that caused routines to prevent
+  dropping more columns than necessary, most notably columns referenced
+  by computed column expressions. The fix is gated behind the session
+  setting `use_improved_routine_deps_triggers_and_computed_cols`, which
+  is off by default prior to v26.1. [#158935][#158935]
+- A bug has been fixed which could cause incorrect
+  results. The bug has existed since v21.2. From v21.2 up to v25.3, the
+  bug only presented when all of the following were true:
+    - The query was run with an explicit or implicit prepared statement.
+    - The query had an equality filter on a placeholder and a UNIQUE
+      column.
+    - The column contained NULL values.
+    - The placeholder was assigned to NULL during execution.
+  In this case, the query could return rows in which the column's value is
+  NULL, which violates SQL NULL-equality semantics. The correct result set
+  should always be empty.
+  Starting in v25.4, the requirements were loosened slightly. It was no
+  longer necessary for the column to be UNIQUE. The bug could reproduce if
+  the column was included in any index. [#159001][#159001]
+- Fixed a bug where the `schema_locked` table storage parameter could be bypassed by combining `SET (schema_locked=false)` with other schema changes in the same `ALTER TABLE` statement using comma syntax. Schema-locked tables now correctly reject such combined statements. [#159017][#159017]
+
+<h3 id="v26-1-0-beta-1-performance-improvements">Performance improvements</h3>
+
+- Triggers now perform the descriptor lookup for `TG_TABLE_SCHEMA` against a cache. This can significantly reduce trigger planning latency in multi-region databases. [#144217][#144217]
+- After triggers now perform the
+  descriptor lookup for `TG_TABLE_SCHEMA` against a cache. This can
+  significantly reduce trigger planning latency. [#158708][#158708]
